Yes. I meant to include that. I did not understand that len()
returned the actual byte length of a UTF-8 encoded string.

I actually just wrote a test that would call a function on the SOAP
server (SOAPpy) that would increase or decrease the test length based
on the previous result until it found x, x+1 where x characters didn't
fail, but x+1 did. x ended up being 65978. The string I happen to be
encoding in this case has all ascii characters so it is the same for
both encodings.

This is an error on the server. The client is actually written in
PHP.
There is no log file, but there is a traceback...

I googled my brains out looking for anything about maximum size both
on the Python SOAP server, and the PHP SOAP client.

I haven't inspected the source, but I have inspected the
documentation. No luck in finding anything about it. I suppose I
could download the client source and see what I can see.

See traceback above.

Thanks for the response John.
